Two balls, of masses mA= 42 g and mB = 60 g, are suspended as shown in the figure. The lighter ball is pulled away to a 66  angle with the vertical and released. Assume that the positive x-axis is directed to the right. b)What is the velocity of each ball after the elastic collision?

Two billiard balls of equal mass move at right angles and meet at the origin of an xy coordinate system. Initially ball A is moving upward along the y axis at 2.0m/sm/s, and ball B is moving to the right along the x axis with speed 3.7m/sm/s. After the collision (assumed elastic), the second ball is moving along the positive y axis.  What is the final direction of ball A? Express your answer using two significant figures.

Two vehicles approach a right angle intersection and then collide. After the collision, they become entangled. If their mass ratios were 1:4 and their respective speeds as they approached were both 13 m/s, find the magnitude and direction of the final velocity of the wreck. 12.5 m/s at 79° 13.1 m/s at 79° 15.7 m/s at 79° 16.3 m/s at 79° Correct.

Two shuffleboard disks of equal mass, one orange and the other green, are involved in a perfectly elastic glancing collision. The green disk is initially at rest and is struck by the orange disk moving initially to the right at voi = 3.00 m/s as in Figure a, shown below. After the collision, the orange disk moves in a direction that makes an angle of 0 = 35.0° with the horizontal axis while the green disk makes an angle of o 55.0° with this axis as in Figure b. Determine the speed of each disk after the collision. Vof = m/s Vaf = m/s After the collision Before the collision Need Help? Watch It Read It

Two shuffleboard disks of equal mass, one orange and the other green, are involved in a perfectly elastic glancing collision.

Determine the speed of each disk after the collision. Vof= m/s Vof- m/s After the collision Before the collision

Two shuffleboard disks of equal mass, one orange and the other green, are involved in a perfectly elastic glancing collision. Voi = 3.15 m/s as in Figure The green disk is initially at rest and is struck by the orange disk moving initially to the right at v a, shown below. After the collision, the orange disk moves in a direction that makes an angle of 0 = 38.0° with the horizontal axis while the green disk makes an angle of = 52.0° with this axis as in Figure b. Determine the speed of each disk after the collision. X V of Vgf= 1.66 Your response differs from the correct answer by more than 10%.

Two billiard balls of equal mass move at right angles and meet at the origin of a xy coordinate system. Ball A is moving upward along the y axis at vAvAv_A = 2.3 m/s, and ball B is moving to the right along the x axis with speed vB= 5.5 m/s. After the collision, assumed elastic, ball B is moving along the positive yy axis a)What is the final direction of ball A? b) What are their two speeds?

Two clay balls collide and stick. Ball 1 has a mass of 3 kg and an initial velocity of 10 m/s in the positive x direction. Ball 2 has a mass of 10 kg and an initial velocity of 12 m/s in the negative x direction. What is the final velocity of the combined mass?

Two billiard balls of identical mass move toward each other as shown in the figure. Assume that the collision between them is perfectly elastic. If the initial velocities of the balls are  v1i = +34.3 cm/s  and  v2i = −20.1 cm/s,  what are the velocities of the balls after the collision? Assume friction and rotation are unimportant. (Indicate the direction with the sign of your answer.) v1f =  cm/s v2f =  cm/s

A cue ball of mass m1 = 0.365 kg is shot at another billiard ball, with mass m2 = 0.595 kg, which is at rest. The cue ball has an initial speed of v = 5.5 m/s in the positive direction. Assume that the collision is elastic and exactly head-on. Write an expression for the horizontal component of the billiard ball's velocity, v2f, after the collision, in terms of the other variables of the problem.  What is this velocity, in meters per second? Write an expression for the horizontal component of the cue ball's velocity, v1f, after the collision. What is the horizontal component of the cue ball's final velocity, in meters per second?
